1966 F100 introduction thread
My main problems now are the carb which is a uremco which would like to replace with the best one possible as it appears to have been drilled into and patched at some point so i am not sure i trust rebuilding it.
The other problem is on the instrument cluster where two hole have been drilled. One i think to be for the red emergency flasher light. No clue what the other is for except maybe a switch that should be to turn the roof marker lights off.
The emergency flashers also do not work properlyas of right now. I found a 20 amp fuse behind the cluster blown so that is the first to be replaced then the flashers but I'm hoping the po didn't cut and splice the flasher circuits into the emergency flasher setup that is supposed to be plug and play.
And pics of the truck.
Remanufacured carb
Split exhaust manifold from something. Not really sure.
The dash with the two holes drilled in it.
The Galaxie for those interested
and the Slicks Forum. 
I am gonna pass on the carb but with dual exhaust I might think 2 barrel or a 390 cfm 4 barrel.
I'd say from the looks of things the large hole was for a rotating switch because of the divot at the bottom. No telling on the other.
You may need to replace the plug in flasher for the 4 ways.
Hope to see you around.

You may have already run across his forum but in case you haven't.
Nice slick and galaxie David.
Anyway, i went through mikes carbs and they sent me basically a new appearing (of course rebuilt) carb in great condition, hooked it up with no adjustments and worked great. You could google that web site, they are very responsive and do good work from what ive seen. Its strange but it looks like the second attachment goes past the float bowl/storage area for fuel....im no carb guy though.
Anyway, id send your pics to them and see what they think.

The other problem is on the instrument cluster where two holes have been factory punched out.
Upper is for red emergency flasher light, lower is for the 4 way flasher switch.

Post the BODY code stamped on the Warranty Plate, riveted to the left door face below the latch.
Your truck has the Custom Cab stainless steel windshield reveal mouldings and 1966 Custom Cab anodized grille, but...
There's no Custom Cab nameplate on the left door, the left front fender emblem is from a 1965 (it's also missing the red plastic insert).
This painted instrument cluster bezel is incorrect for your truck, if it's a '66 F100 2WD Custom Cab (BODY code will determine what it was originally).
It appears to have been swapped in, as its seal is missing, the one (visible) screw doesn't line up properly. Painted clusters were only installed in 1961/66 Standard Cabs.
1965/66 F100/250 2WD Custom Cabs & Rangers have a plastic chrome sweep speedo cluster. The 4 way switch and lamp located next to the choke cable below the cluster.
It might have been around the time they went to fuel injection on that motor.

Po had painted over plate completely so no fancy fomoco logo or other info for what the numbers mean.
Still has its 240 in it.
20 amp fuse location
Black blue wire in upper left fuse in lower right<br/> Sorry about flash over exposure.
I have a reproduction manual and wiri g book for the truck so i will give it a shot myself but thought i would put them up for those that might know just from sight.
Looks like a blue and red or orange wire but there is lots of over spray.
Cut wire. Looks brown and I am almost positive this is for the heater switch add it had been jumpered with another wire and the wiring diagram i have says a brown wire.
The emergency flasher switch and flasher in the dash next to the choke cable as opposed to the cluster for some reason.also not sure how to take it off to move it or what should take its place from the factory if anything.
The two wires for the red lamp i presume.
BM - Caribbean Turquoise (B) (looks like your firewall is still this color) and Wimbledon White (M)
L81 - Medium green crush vinyl and medium green cody pattern woven plastic. It's a standard cab.

The OP's Standard Cab has been pieced together using some parts from Custom Cabs.
1961/66 ALL: The 4 way flashers were a factory installed option or a dealer installed accessory.
The OP's painted steel instrument cluster bezel is not original to the truck, due to the factory installed punched out holes for the 4 way switch and lamp.
A previous owner either bought a NOS dealer installed 4 way kit, or got the parts from a junkyard. Installed the switch in the correct location, but where is the lamp?
1965/66 F100/250 2WD Standard/Custom Cabs & Rangers; 1966 F100 4WD Standard/Custom Cabs:
4 way flasher switch located below the instrument cluster in a hole to the left of the choke cable. If there was no switch, the hole was plugged with a chrome steel button.
The 4 way flasher lamp hole was located to the left of the switch, was punched out if factory installed, drilled out if dealer installed.
Look at the pic below, this is the correct plastic chrome sweep speedometer instrument cluster bezel that came on 1965/66 F100/250 2WD Custom Cabs & Rangers; 1966 F100 4WD Custom Cabs.
The oil (9273) and amp (10850) gauges were a factory installed option, so some trucks have warning (idiot) lamps instead.
